Path: lucene query

In my javascript lucene query against staging sandbox store.luceneSearch("PATH:" + "\"*//miscellaneous/weekly_activities//*\"") returns correct search results but when the I change the store to demo–admin and do store.luceneSearch("PATH:" + "\"*//miscellaneous/weekly_activities//*\"") I don't get any search results. The sandboxes are also indexed and the results are returned in the other search queries as well any suggestions and help is appreciated.
